  • fish feed. The wastewater from soybean
  • processing can be converted into a nourishing, protein-rich food for farmed Asian sea bass, a team of scientists has discovered.
  • They worked with a local food processing company to rescue hundreds of liters of soybean wastewater, which they discovered was rich in two types of protein-accumulating microbes in particular, known as Acidipropionibacterium and Propioniciclava.
  • ...3 more annotations...
  • The sea bass that were fed the alternative microbe protein diet did have significantly lower weight to begin with, but that evened out as they grew. And, notably, the group that received the traditional feed diet had greater variability in their weight gain as they grew—whereas those fed the alternative microbe protein diet showed a more even accumulation of weight over the experiment’s course.
  • Meanwhile, the wastewater from other soybean uses goes unused—but according to the recent results, could feasibly tackle both of these sustainability challenges at once. Furthermore it’s not just soybean waste water, the researchers say: several agricultural processes create wastewater side streams that are rich in the combination of carbon, nitrogen, and phosphorus that’s needed to sustain a growing population of hungry, protein-accumulating bacteria.
  • Microbial community‐based protein from soybean‐processing wastewater as a sustainable alternative fish feed ingredient.

    Possible more efficient fish feed to reduce waste and benefit the environment as well as the economy.

  • Called gravimeters, such devices can detect tectonic plates shifting, sense the movement of underground water, reveal hidden oil and gas reserves, and track magma within volcanoes to provide data for predicting eruptions, along with many other applications.

      How is a Gravimeter able to detect the movement of tectonic plates shifting, does it detect sound waves or vibrations?

    This is a crowd-sourced document I created for a session with high school research teachers in Washington D.C. in 2022. SAVE this document and use it to explore some of the more commonly-used model organisms for all sorts of biological research. There is a TON to explore here!

    This is a slide deck I used for a presentation to research teachers in Washington D.C. last year. I will also save a link to the crowd-sourced document we created in this session where teachers too our suggested model organisms, and then added in their suggestions as well.

Do Invertebrates Have Emotions? | The Scientist Magazine® - 1 views

  • He adds that he doubts that the findings are applicable to other insect species, which still might act purely on instinct.
  • Invertebrate nervous systems, physiology, and sensory experiences are dissimilar to ours, and designing experiments to measure their emotions has been challenging. 
  • If the responses weren’t purely reflexive, it would open up the possibility that the animals could feel pain. 
  • ...1 more annotation...
  • After placing acetic acid—a mild irritant—on the crabs’ antennae, they found that the crabs rubbed their antennae against the glass of their aquarium, seemingly in an attempt to take the acid off.

      The use of an invisible irritant rather than a notable injury shows that they can feel the pain, instead of just noticing an injury to their body.

      Some species like the infected coral Maybe it has different properties or something

    You know, there are repositories of publicly available image/video data from coral reef surveys.... somewhere online. They make them available for people to devise creative ways of pulling data out of such raw material. Might be something to look into.

    I wonder what sort of electronics were needed to accomplish this. I also wonder how difficult it would be to attach those to a living insect without sacrificing it.

    Interesting. The video clips are especially valuable for understanding their methods. So, these tests have been done... but what other sorts of learning tests might be possible? Are there any that might even show value in this species beyond just "what is possible for the bee nervous system to accomplish?"
